This invention has reference to agricultural machines and moreparticularly a machine known as a gang plow, the primary object of thelinvention being to provide a gang plow wherein certain plows may bereversed so that the ground may be plowed and simultaneously conditionedfor plantgAnother important obj ect of the invention is to provide aplow of this type including a plurality of independent plow beams, theLplow beams being arranged in pairs, the plows of each pair beingremovably con-` nected so that the blades may be' changed to meetvarious requirements of use.

A still further object of the invention is to provide means whereby theplows will be self-cleaned or self-releasing, should they meet with anobstruction in the path of travel n of the plows.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combinationandarrangement of parts and in r the details of construction hereinafterdescribed an'd claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Referring to the drawing:

, Figure 1 is a plan view of an agricultural machine constructed inaccordance with the invention.

Figure 2 is a side elevational view thereof.

Figure 3 is a sectional view taken on line 3--3 of Figure 1.

Figure 4 is an enlarged elevational view of a plow, and taken from therear thereof.

Referring to the drawings in detail, the reference character 5designates the front axle of the machine on which the wheelsrG aremounted, adjacent to the outer ends of the axle.

The reference character 7 designates collars that are secured to theaxle 5 and against which the wheels 6 rub, to hold the wheels in properposition on the axle.

The reference character 8 designates one of the plow beams, while thenumeral 9 desigthe springs will beams 8 and 9, are plowfbeams 13 and 14.

respectively which are also pivotally mounted on the axle 5 andrestricted against lateral movement by means of collars 15. This pair ofplow beams 13 and 14 are connected hy means of the U-shaped memberi16wliich holds the beams y13 and 14 in proper spaced relation with eachother.

The plow beam 14 is longer than the plow beam 13, to,v` theV end thatthe plow beams may be removed and reversed for purposesto be hereinaftermore fully described. i

To further insure against the plow beams 13 and 14 being moved together,a spacing bar 17 is provided adjacent to the free ends l of the beams 13and 14. As clearly shown by c Figure 2, the plow beams being of the wellvknown construction, are formed with rear curved extremities to which.the plows' 1'8'are pivotally connected. i

Extending rearwardly :from each plow is an arm y19 to which links20`arepivotallyconnected, the links 20 lyingony opposite sides of the curvedportions of theplow beams. These links 20 have pivotal connection at 21with bell crank levers- 22 that are pivctally con` nected with theplow'` beams and have connection with the coiled springs 23 that alsoconnect with the plow beams,through the medium of theVv members 24, towhich the coiled springs are secured.-

Thus it' Win be geen that 'as the piowsiis'are Y forced into the groundsurface, the springs will be placed under tension, and that when rtheplows meet vwithA anI obstruction, which would otherwise bend4 or breakthe"plowsf,l the springs will allow the .plovvs to swing rearwardly andclear the obstructiomwhereupon return the plows"y to their normanpositions', Connected with the plow beamsl are the bars which rest onthe member 26 that includes a horizontal bar spaced from the axle 5 ofthe machine, the forward ends of the bars 25 being connected by means ofthe bars 27 to which the draft appliance is connected. e rl`hus it willbe obvious that a pull directed to the members 27 will result in adownward movement of the plow beams against the action of the coiledspring to move the plow beams into the soil.

The frame of the machine is indicated generally by the numeral 28 andhas pivotal connection with the upstanding bars 29 that are mounted onthe axle 5, the` frame being substantially triangular in formation andprovided with a bearing 30 at the rear thereof in 'which the verticalshaft 3l of the wheel 32, supported at the rear of the machine,operates, to guide the machine. f j v As shown, a spring pressed pin 33is associated'with the shaft 3l and is designed to t in a suitableopening of the shaft 3l to normally hold the shaft 31 against movement.A foot lever 3a is .mounted on the frame and f connects with the pin 33,through the cable 35 to the end that when the lever 34E is movedforwardly, the pin will be withdrawn to pery mit movement of the shaft.

Mounted on the upper end of the shaft 31 is a coiled spring 33 which hasone end secured to the shaft, the opposite end thereof being secured tothe bearing 30 so that th'e coiled spring 33 will act to normally returnthe jwheel 32 to its initial position where it may again be loclred bythe pin 33.

Controlling levers 36 connect with the frame and are pivotally supportedat 37, the ends of the levers 36 being supplied with springs 38 thathave their lower ends connected with one of the plow beams of each pairso that as the levers 36 are raised or lowered, the plow beams will bealso raised or lowered to vary the depth of operation.

Segmental racks 39 are provided and are engaged by the locking members39 carried by the levers 36 so that the plows may be held in theirpositions of adj ustment.`

The tongue of the machine is indicated by the numeral 4:0, the samebeing connected to the axle 5 by means of the bars 41 which have theirinner ends formed into bearings 42.

In the operation of the machine the machine is `moved over thegroundsurface in the usual manner, whereupon the plows will operate to breakthe soil and condition it for planting. Y

Owing to the construction of the device it is obvious that the beams 8and 9 may be reversed and the plows reversed, making it popssible toplow and ybed the ground with a single operation of the machine.

vI claim:

An agricultural machine including a frame, an axle, pairs of plow beamspivotally mounted on the axle, means for connecting the plow `the axle,a wheel supported at the rear ofV the frame, and plowssupported at thefree ends of the plow beams. i

In testimony that I claim the foregoing asafxed my signature.

my own, I have hereto Y JOI-IN COLLINS.
